Quote from Rosy Dumplings »
This is not an obstacle, exactly. The Magic-ized version of the stranger thing cards aren’t going to be like the Godzilla cards that list the name of the original.
Has that been confirmed?
The only thing that will stop a deck from including 4 copies of each is that the oracle entry for the card will dictate that they are the same card.
Having to look on gatherer to see if a card in your deck is the same as another might cause problems, the Godzilla style of cards would alleviate that without having to look up information on the internet.
